After about three minutes, the algal cell is depleted and Placopus continues locomotion. During the ingestion phase, the hump of the cell flattens and the lamellipodium retracts.

Biomyxa sp. (Biomyxidae): Strains of two undescribed marine species isolated from ships’ ballast sediments arriving at Haifa (Israel) and videotaped at normal velocity and eightfold timelapse after transferring of the samples to Berlin. The sequences show cells with (1) a reticulate network of filose pseudopodia and (2) a pseudopodial lamella forming an adhesive plaque at the bottom of a polystyrene Petri dish used for cultivation and visualization. Possible origin of strains: Port of Long...
